Title: Method of and apparatus for rolling strip material
IPC: B21B29/00
Filed: 1959-08-25
Abstract: 870,777. Rolling. UNITED ENGINEER. ING & FOUNDRY CO. Aug. 25, 1959 [Aug. 25, 1958], No. 29009/59. Class 83 (4). In a method of rolling strip between a pair of work rolls the work rolls are supported by a pair of backing rolls to the ends of which a contour-controlling bending moment is applied to compensate for roll deflection. The working rolls 14 of a rolling mill are supported by backing rolls 16, the chocks 17 of which are slidable in windows of the housings 12, 13. The pass is adjusted by a worm 18 and screwdown 19. Contour-controlling bending moment is applied to the rolls 16 by double-acting cylinders 25, 32 having piston-rods 24 releasably attached to bearing housings 20 engaging the roll-necks outwardly of the screwdown support. Fluid is fed to the cylinders 25, 32 from a sump 33, Fig. 3, by a pump 36 through a three-way pressure-regulating check valve 42, a solenoid-operated valve 46, fourway solenoid-operated directional control valves 49, 49a and pairs of reducing valves 52, 53 and 55, 56. Valves 55 admit fluid to the piston-rod ends of the cylinders 25, 32 directly the valve 46 opens so that the supporting rolls 16 are held apart until the light beam of a photo-cell is interrupted by the strip entering the mill which initiates operation of the valves 49, 49a so that fluid is then supplied to the head ends of the cylinders 25, 32 through valves 52, 53. In the event of the strip breaking or the end of the strip reaching the mill the light beam on becoming uninterrupted initiates a reversal of action of the cylinders 25, 32 to hold the rolls apart. During rolling pressure is applied to the necks of the supporting rolls in a direction to increase the crown. In a modification the contour - controlling bending moments are applied to the roll-necks by one double-acting cylinder at each end of the rolls, the piston rod of each cylinder applying force directly to the lower supporting roll while force is applied to the upper supporting roll by rods connecting each cylinder to the appropriate neck of the upper supporting roll. The cylinders are slidable on the housing and are each balanced by a piston cylinder assembly mounted beneath the housing. In a further modification the invention is applied to a cluster mill having intermediate rolls between the working and main support rolls. The rolls may be crowned or uncrowned the deflection being used to modify the crown.

Title: Improvements in radio receiving aerial systems
IPC: G01S1/02
Filed: 1939-11-03
Abstract: 536,259. Aerials; wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and STEWART, J. Nov. 3, 1939, No. 29362. [Class 40 (v)] The fore-and-aft and lateral trim of an aeroplane in flight are indicated by variations in the signal strength received by vertical and horizontal aerials from vertically-polarized waves. The effect depends upon the change in signal strength when an open aerial is connected either to the centre, as at A, Fig. 1, or to one side or the other as at A1, A2 of the fuselage B acting as a counterpoise. In Fig. 2, a vertical aerial OA supplies a constant signal to a centre-zero indicator M through two rectifiers R, R1, which are alternately switched into circuit at S so that the needle is kept at zero. Simultaneously an horizontal aerial A (the disposition of which has previously been adjusted to give zero pick-up when the craft is on a level trim) is synchronously switched at S1 from one end to the other of a centre-tapped coil CC, so as to feed equal signals of opposite phase to the indicator. Any alteration in trim will upset the balance of these signals, and the indicator will move accordingly to one side or other of the zero point. An aerial for showing fore-and-aft trim is preferably arranged parallel to the length of the fuselage ; or two horizontal aerials, one for showing the lateral and the other for fore-and-aft trim, may be coupled to the indicator through separate amplifying channels ; by using a " flicker " system, the two switching operations can be combined, and the signals passed through a common amplifier. A radiogoniometer may be used to adjust the relative disposition or coupling between two horizontal aerials, one mounted above the fuselage and the other below for balanced flight, Figs 3 and 4 (not shown).
